During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

The main aim of this study is to examine the political debate in Sweden around a potentionalcriminalization of buying sex abroad. A second additional aim is to analyze the debate from anintersectional feminist gender perspective, by bringing attention to ideas about gender, ethnicity andpower expressed in the empirical material.The questions at issue are:What are the arguments for and against the potentional criminalization of buying sex abroad andwhich central discursive battles can be discerned throughout the debate?What impact do ideas about gender and power have on the construction of a general advocatediscourse versus a general antagonist discourse?The methodological point of departure is Critical Discourse Analysis, drawing on the theories ofNorman Fairclough, Ernesto Laclau and Chantal Mouffe. The empirical material consists of 27articles and editorials publicized in Swedish newspapers between January 2011 and November2014.The result shows that the polemics manifested in the debate are based on different ideas aboutgender, ethnicity and power. A crucial discursive battle stands between human rights andinternational law as a superior principle.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

The purpose of this essay is to examine sfi (Swedish for immigrants), which is an ingrational-political tool with objective of teaching immigrants to read and write in Swedish. With the use of critical discourse analysis we examine the discursive practices within sfi. We also examine our methodological and theoretical approaches, and our application of them. Our research questions are as follows:? How are the discursive usage of ?person centered? and ?society centered? expressions being used?? How well does our methodological and theoretical resources work?In our theoretical viewpoint we use ?post colonial theory?, which is a perspective concerned with global power relations seen from a historical perspective.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

The aim of this Masters thesis is to examine the view of market-led culture, focusing on literature, within Swedish governmental cultural policy. The main issue is to discover changes in attitude towards cooperation between culture and business by comparing the attitudes and ideas expressed in the governmental policy documents from the 1970s with the governmental policy documents from the 1990s. To illuminate, and with an effort to explain, these attitudes and ideas expressed in the documents their political and social context has been studied as well. The theoretical starting point is two political ideologies, and Danish cultural policy researcher Dorte Skot-Hansens theories of cultural policy in the Nordic countries. The methodological starting point is two variants of analyses that are textual ones.

The background to the work bases on the consumers view around Swedish and foreign meat products, and how the attitude around the meat products is pursued in the shops. The consumers request high meat quality and security . Many consumers value local produced and ecological meat products but the price is too high. We have done verbal interviews with consumers on three different shops, where we asked questions and had dialogues around Swedish meat products where the consumers have told us their arguments and opinions about Swedish and foreign meat. The result shows that the majority of consumers consider that it is important to know that meat is produce in Sweden.

In the early 1860´s, the author and opinion former Fredrika Bremer made a large donation of books to Högre lärarinneseminariet, which is the first governmental institute for higher education of women in Sweden. The aim of this thesis is to describe the collection of donated books as well as to extract information regarding Bremer's international network of contacts, her views on women's education and her relation to Högre lärarinneseminariet. Furthermore, the aim is to highlight the unique relationship between Fredrika Bremer's private collection of the books and the library of Högre lärarinneseminariet from a gender perspective. A handwritten list of the 321 titles constitutin the donation has been preserved in the seminar archive and three quarters of the books have been re-discovered in a bookcase at Årsta castle. The donation is characterized by its double origin as stamps and personal dedications remain as permanent traces in the books.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

The aim of this study is to increase knowledge and understanding of free play or free fun time importance for children of age around five years in preschool, in order to promote children?s development and learning. The focus was on exploring and better understanding of teacher?s and educators? approach to the free fun play time as a tool in their educational work, and also about their own role in this context as well as analyzing of forms, rules and structures spontaneously created by groups of children having free play fun time. Another important moment of this study was to give more light on approaches to this issue in education theories by Piaget, Vygotsky and Freud among others.As to the practical experimental part of the study it has been performed at a preschool and kindergarten in a suburb at the outskirts of Stockholm, with four employed educators there and with groups of children of age around five.

This master project in landscape architecture is named Interactivation Design - places for social imagination and conversation in Lindängelund. There are two main purposes of this thesis the first being to bring forth a study of interactivity implemented in the subject of landscape architecture. The second purpose of this thesis is to present a proposal to design a confluent landscape weaving together the upcoming botanical garden of Lindängelund and the residential area of Almvik, both situated in southern Malmö, Sweden, and also weaves people and their experiences together. This project may be described as investigative and experimentative reaserch by design.The first part of this project, Interactivation, is consisting of a theoretical report which discusses different ways of approaching when, how and why we interact in public space. Literature studies in for example space, placemaking, social life, people, participation and Japanese emptiness concepts has been undertaken to gain knowledge in the aim to create interactive landscape design.The second part, Context and Design Proposal, introduces the project context area of Southern Fosie in Malmö which consists of different kinds of residential areas, people of different nationalities and a large building site for a botanical garden and recreational area.

Elective joint surgery increases for every year and the operations are associated with postoperative pain. Postoperative pain is a well known phenomenon and pain physiology and analgesics are well known by caregivers, but the significance of the interaction between patient and caregiver is not illuminated. There are still patients experiencing unnecessary postoperative pain. Among patients in elective surgery, 25% runs a risk for underestimated pain. The aim of the study was to describe patient?s experiences of nursing interaction in the context of postoperative pain during hospitalisation after going through knee- or hiparthropasty.
